Understanding the 10-108 Police Code Meaning

The 10-108 police code is used to indicate that a law enforcement officer is either severely injured, incapacitated, or facing an immediate threat. When this code is broadcast over the radio, it instantly alerts other units to prioritize the situation and respond as fast as possible. It is a distress signal that triggers a high-alert status across the department and can even involve SWAT teams, medical response units, and other tactical support.

The usage of standardized radio codes such as 10-108 enhances operational efficiency during high-stress situations. Instead of describing a dangerous scenario in lengthy, unclear terms, officers can use short codes to communicate vital information quickly and precisely.

Why Do Police Use Codes Like 10-108?

Police departments across the United States use “ten codes” or radio codes to communicate effectively over radio transmissions. These codes were initially developed in the 1930s and 1940s to reduce the length of radio messages and make communication more standardized. Each number has a specific meaning, and 10-108 is reserved for one of the most serious incidents—an officer being injured or in immediate danger.

Using a code like 10-108 helps prevent confusion, ensures clarity, and allows for a faster response time in life-threatening situations. In moments where every second counts, such as when an officer is down or facing a dangerous confrontation, quick and accurate communication can save lives.

What Happens When a 10-108 Is Called?

When the 10-108 police code is issued, multiple actions are immediately taken:

Nearby officers are dispatched to the scene without delay.
Dispatch notifies emergency medical services to respond.
Supervisors and specialized units (like SWAT) may be alerted.
Radio silence may be ordered to reduce interference during a critical incident.

This code is treated with the utmost seriousness. It symbolizes more than a procedural alert—it’s a call for unity, protection, and swift action to aid a fellow officer in distress.

History and Evolution of Police Codes

Police radio codes date back to the late 1930s. Between 1937 and 1940, the Association of Public-Safety Communications Officials-International (APCO) developed the original ten-codes to simplify radio communication. In 1974, APCO further expanded and refined these codes to address the growing complexity of police operations and technology.

The very first concept of brevity codes actually appeared in the June 1935 issue of The APCO Bulletin, where Morse code signals were adapted from U.S. Navy procedure symbols. Although they were originally meant for Morse code communication, these systems laid the foundation for what became the standardized voice radio codes still in use today.

Most Common Police Codes in Use Today

One of the most iconic codes in police radio language is the 10-7 code, which means “out of service.” Officers use this code when they are no longer available for calls. Another meaningful code is 10-42, signifying the end of an officer’s tour of duty—a powerful message often used during retirement ceremonies or to honor fallen officers.
